This box contains a set of parchment cards. A full deck has 34 cards. A deck found as treasure is usually missing 1d20 - 1 cards. The magic of the deck functions only if cards are drawn at random. You can use an action to draw a card at random from the deck and throw it to the ground at a point within 30 feet of you. An illusion of one or more creatures forms over the thrown card and remains until dispelled. An illusory creature appears real, of the appropriate size, and behaves as if it were a real creature except that it can do no harm.
